You are absolutely right.  I can, however, play with octane, CR,
h2o/methanol injection and timing before I head to the salt and get an idea
what I would be able to do safely when out there.  I could even do a
shakedown with computer control early in the week to gain data at elevation
before attempting to qualify without the computer on board. Knock sensing
and A/F monitoring under load will help me get it right before leaving
Minnesota!
Thanks
Greg
